Problem 3: Determine the acceleration of block B, acceleration of block A, and the tension in the cable if the system is released from rest. The coefficient of static and kinetic friction between block A and the wedge surface are js = 0.2 and uk = 0.15, respectively. Neglect masses of the pulleys and associated friction in the pulleys. Consider ma = 15 kg and mp = 8 kg. FBDs and kinetic diagrams for blocks A and B is mandatory....
A cable passes over a pulley. Because of friction, the tension in the cable is not the same on opposite sides of the pulley. The force on one side is 121 N, and the force on the other side is 109 N. Assuming that the pulley is a uniform disk of mass 2.22 kg and radius 0.770 m, determine its angular acceleration. Submit Answer Tries 0/10 This discussion is closed Send Feedb
